Abstract :
A high resolution simple swept source for OCT measurements is presented. Low skew frequency domain triggering via electronic processing allowed resolutions of one FFT bin for a single reflection. The high resolution capability was demonstrated in a system containing ~10 ??m spaced interfaces.
